Let's assume that a carpenter borrowed $2 comma 000 to be paid off in a year to finance a machine that would make him work faster. As a result, he is able to take on more projects and collect $400 more earnings in the first year, after paying off the principal of $2 comma 000. However, there is a 12% rental fee (interest) on his loan that he also has to pay off. The carpenter earned an extra $ nothing in the first year. (Round your response to the nearest dollar)
